Amlodipine high blood pressure drug. This drug is used to treat hypertension (high blood pressure) and angina pectoris (heart pain). It is a calcium channel blocker, which prevent calcium ions from entering muscle cells when excited, leading to weaker muscle contraction. This dilates blood vessels and reduces the force of contraction of the heart.
